Operator '<' cannot be applied to operands of type 'bool' and 'double'

Wow...I've never seen this before. Any way to get around it?

foreach( double r in portfolioReturns)
        {
            if (-8.0 < r < -7.0)
            {
                n8++;
            }}

You could also use LINQ, in addition to the fix everyone so quickly provided

n8 += portfolioReturns.Count(r => -8.0 < r && r < -7.0);

You are effectively doing this

if ((-8.0 < r) < -7.0)

Since (-8.0 < r) evaluates to a boolean, you can't compare it to a float. Do this instead:

if (-8.0 < r && r < -7.0) {
  //code here
}

let me guess, you are coming from python? It is the only language I know of where that works :-)

looking at (-8.0 < r < -7.0), first, -8.0 < r gets evaluated, which is true. true < -7.0 barfs.
